=Z0 aZZ whom it may cancer/1,.

Be it known that I, ALFREDO ROSA Y PAS- CUAL, a subject of Spain, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and useful Improvement in Firearms, of which the following is a full, clear, and eX- act description.

The object of my invention is to so construct a gun that a barrel of larger caliber than ordinary, or a barrel of any predetermined caliber, maybe connected in a detachable manner to the stock and firing mechanism of the gun, the application of the enlarged barrel being especially adapted to rifles or arms adapted to be fired from the shoulder.

A further object of the invention is to provide a rest for the firearm capable of being readily and quickly introduced in a steadfast manner in the ground, together with a device whereby the barrel may not only be given any desired inclination, but may be turned as upon a pivot and secured in the position to which it may be adjusted.

The invention consists in the novel construction and combination of the. several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speci fication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a gun having the improvement applied, the barrel being in section, together with a portion of the attachments to the barrel. Fig. 2 is a longitudinal section through a portion of the enlarged barrel and a section through a portion of the attachments to the said barrel. Fig. 3 is a vertical section on the line 3 3 of Fig. 2, and Fig. 4 is a perspective view of a sleeve adapted for attachment to the support for the gun and adapted as a guide for the vertical movement of the enlarged barrel.

A represents the stock of a gun, B the casing for the firing mechanism, and 0 an exteriorly-threaded stub of a barrel connected with the firing mechanism.

The attachment consists of a barrel D, which is of much larger caliber than the barrel which would be ordinarily attached to the stock and firing mechanism of a rifle or a gun of similar description. The enlarged barrel D is provided with an interior thread 10, and is screwed upon a thimble the said thimble in its turn being screwed upon the stubbarrel 0, connected directlywith the breech end of the casing for the firing mechanism.

A semicircular bar 11 is secured to the barrel D, one end'of the bar being connected with the barrel at its breech end and the other end of the bar being attached to the barrel a predetermined distance from the breech end, and the bar 11, which is a guidebar and is in the form of an arc, is preferably secured to a side of the barrel D, as shown in Fig. 3. A strap 12 is passed around the barrel D at about the center of the arc 11, and the terminals 13 of the strap are carried in parallel order beneath" the barrel, as shown in Fig. 3, and between the terminals of the strap 12 the upper or shank portion 14 of a cup or socket fitting 15 is pivoted, the said socket-fitting being provided usually with set-screws 16, which enter-the socket-fitting at opposite sides, as shown in Fig. 2. v

The upper end of a supporting rod or staff 17 is entered in the socket-fitting, the upper end of the said supporting rod or staff being provided with an annular groove 18, receiving the inner ends of the set-screws 16, enabling the gun to be moved laterally andsecured in the position to which it may be moved. A sleeve 19 is held to slide on the supporting rod or staff 17, being adj ustably attached thereto by a set-screw 20. The sleeve 19 is provided with an extension in which an opening 21 is made, the said opening being made to receive the are 11. Therefore when the sleeve is secured to the supporting rod or staff 17 the gun may be given any desired inclination, since the arc may freely play through the extension of the sleeve. After the desired inclination has been attained the gun is secured by means of a set-screw 22, which is passed through the extension of the sleeve 19 to an engagement with the are, as shown in Fig. 3, the sleeve being illustrated in detail in Fig. 4:.

The lower end of the supporting rod or staff 17 is sharpened in order that it may be readily driven into the ground, and the extent to which the stafi or rod shall enter the ground is limited by means of a disk 23, at-

tached to the rod or staff by a set-screw 24. This disk serves not only to control the extent to which the rod or staff shall enter the ground, but also serves as an extended bearing on the surface of the ground.

From the foregoing description it is evident that the breech portion of an ordinary firearm may be attached to a barrel of exceedingly large caliber,- capable of service as light ordnance, and that a fort hastily constructed may be quickly and conveniently equipped with means of defense capable of most eflicient service. I

This improved firearm is easily handled and carried and may thus be used by small bodies of troops, which would not be strong enough to transport and protect the regular ordnance of the same caliber.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a firearm, the combination, with the stock, the casing containing the firing mechanism, and a stub-barrel attached to the forward end of the said casing, of a main barrel attached to the stub-barrel, the main barrel being of larger caliber than the stub-barrel, a support for the. barrel pivotally attached thereto, the barrel being capable of lateral movement on the said support, an are attached to the main barrel, a guide for the arc, and means for securing the arc to the said guide, for the purpose set forth.

2. In a firearm, the combination, with a barrel provided with an arched bar extending below its under face, and a socket-fitting pivotally connected with the barrel at the adjustable upon the said support and provided with an opening adapted to receive the arched bar of the barrel, and means, substantially as described, for fastening the arched bar in said sleeve, for the purpose set forth.

3. In a firearm, the combination, with a barrel provided with an arched bar extending below its under face, and a socket-fitting pivotally connected with the barrel at the central portion of the arched bar, provided with set-screws, of a support, the upper end of which is'adapted to enter the said socket fitting, the support being provided at its upper end with an annular groove adapted to receive the set-screws of said fitting, a sleeve adjustable upon the said support, and provided with an opening adapted to receive the arched bar of the barrel, and means, substantially as described, for fastening the arched bar in said sleeve, and a disk adjustably secured upon said support, the disk serv ing to control the extent to which the support shall enter the ground and forming also an extended bearing upon the surface of the ground, for the purpose specified.
